MAST FOR WELL-DRILLING MACHINES.

Specification of Letters Patent.

Patented Nov. 27, 1 906.

Application filed April 5, 1906- Serial No. 309,962.

To a/ZZ whom/ it 11i/ay concer-7c.

Be it known that I, MEET MCCAIN, a citizen of the United States,residing in the city of Portland, in the county of Jay, and in the Stateof Indiana, have invented a new and useful Mast for Well-DrillingMachines, of which the following is a complete and lucid specification,being such' as will enable others skilled in the art to which theinvention relates to make and use the same.

In the present invention my objects are to provide a new and useful mastor derrick for deep-well-drilling machines, to provide a mast which willbe light in construction and easily managed, to provide a mast which maybe easily and quickly placed in position or as easily dismounted andeasily trans ported, to provide means for raising and low.- ering themast by power, to provide for properly securing and retaining the mastin its operative position, and to provide means whereby the mast may bedismembered or assembled when desired.

Other particular objects and advantages will "present themselves in thecourse of the ensuing specification.

With the above-enumerated objects in view my invention consists in theform, proportion, the indispensable requisites, and the relations of theseveral parts and the means for accomplishing the several correlatedobjects, all of which will be described in concrete detail and withabsolute exactitude in the ensuing specification.

The preferred construction of my invention and that which in actualpractice I have found to give the most satisfactory results is shownmost clearly in the accompanying drawings, in which- Figure 1 is aleftehand side elevation of the lower portion of my invention inoperative position and as applied to a well-drilling ma chine. Fig. 2 isa view similar to the above, but showing the upper portion of theinvention. Fig. 3 shows a rear elevation of the lower portion of themast in operative position. Fig. 4L is similar to the last, butshowingthe upper portion of the mast. Fig. 5 is a left-hand sideelevation of a portion of a machine, showing the lower portion of themast as suspended at an angle, as in the act of being raised or lowered.Fig. 6 is a side elevation of the upper portion of the mast in theposition shown in Fig. 5. Fig. 7 is a de tail view of the contact-rollerfor the main cable. Fig. 8 is a top plan-view of the upper end of themast. Fig. 9 is a right-hand side` elevation of the lower portion of theinvention. Fig. 10 is a right-hand side elevation of the upper portionof the invention, and Fig. 11'is a top plan view of the reel mechan* ismfor raising and lowering the mast by power. v

Like reference characters denote like parts throughout the several viewsof the four sheets of drawings.-

In order to render the construction and op.- eration of my inventionstillmore facile, I will now take up the description in detail and willrefer to the various essential elements as briefly and as compactly as Imay and in simple and concise terms.

In the drawings, the letters A and A denote the main sills of awell-drilling machine in connection with which my invention is intendedto be employed. The letter B denotes the front cross-frame, and theletter C denotes the cross-beam in the rear. The letter D denotes across-beam located toward the rear, and the letter E denotes thecross-beam located near the center, while the letter F denotes thecross-beam located over the rear wheel. All of said parts are suitablybraced and secured together and collectively form the main frame of themachine. The main frame thus formed is mounted on suitableground-wheels, -(designated by the indices 20, 20', 22, and 22, asshown.)

The above and other parts of the machine are incorporated herein simplyto show the relations of my invention with reference thereto, themachine proper being speciiically described and claimed in anapplication filed concurrent herewith.

The numeral 69 denotes the horizontal base of the mast, which is adaptedto be disposed across4 underneath the main frame of the machine and torest on the mudsills 51 and 52, which are disposed on either side. Atthe points where the base 69 rests on the mudsills it is formedrounding, as indicated by the dotted line in Fig. .1, in order that itmay rotate on said sills, as will presently be set forth. Said base 69is adapted to be retained in place on the mudsills 51 and 52 by thestraps 70 and 71, respectively, whereby the base may not move forwardand backward, but may turn revolubly, as will presently be explained,Said straps extend over the rounded portions of the base,rand their endsare secured to the mudsill by bolts or the like, substantially as shown.

IOO

IIO

The numerals 72 and 73 denote the lower left and right posts,respectively, of the mast, which posts are mortised into the outerportions of the base 69 and thence extend upward convergently, asindicated.

The numerals 91 and 92 designate the upper posts of the mast, which, infact, are simply the continuations of the lower posts, the. respectivemembers being spliced together in any well-known manner. The upper endsof the posts 91 and 92 are rigidly secured together by the horizontalapex-frame 93, and the outer ends of said frame are supported andconnected to the posts by braces, (designated by the indices 94, 94',94, and 94.) The numeral 95 denotes a channel wheel or pulley, which ismounted between the upper ends of the posts 91 and 92, extending upthrough a slot therefor in the frame 93. Immediately below the wheel 95the posts 91 and 92 are rigidly connected by the cross-tie 96. Somedistance below the tie 96 the said posts are again connected by thetie-rod 97, and below the latter the said posts are again connected bythe combination of the cross-tie 98 and the rod 99, as shown. Thenumerals 100 and 101 denote the two crossing braces, extending crosswisebetween the opposing inner faces of the posts 91 and 92, extending fromnear the tie-rod 97 to the cross-tie 98, as shown in Fig. 4.

Extending out from the rear face of the cross-tie 98 are the two hangers102 and 102', by and between which is mounted horizontally therelatively long free roller 103, which is parallel with the cross-tie98. Said roller is invented for the main cable 40 to contact with inorder that the cable may not be damaged by contact with the cross-tie 98or other parts of the mast, as is usually the case when in operation.Said cable 40 extends up from the bull-wheel spindle 39 of the machine,over the wheel 95, and then extends down, wherey it may be connected forwork in the usual well-known manner.

The lower positions of the posts 72 and 73 are braced and are held inconnection with the base 69 by coupling-rods. Secured on the face andback of theipost 72 by the bolt 104 are the res ective eye-plates 105and 106, in which are ooked the upper ends of the Arespectivecoupling-rods 107 and 108, said coupling-rods being connected with therespective turnbuckles 109 and 110, and the lower ends of saidturnbuckles are hooked into the respective eyebolts 111 and 112, andsaid eyebolts are secured inthe surface of the base 69 some distanceapart from the post 72. Like unto the above, secured on the face andback of the post 73 by the bolt 1 13, are the respective eye-plates 114and 115, in which are hooked the upper ends of the respectivecoupling-'rods 116 and 1 17, said rods being connected with therespective turnbuckles 1 18 and 119, and the turnbuckles are hooked intothe respective eyeboltsI 120 and 121, said eyebolts being secured intothe surface of the base 69 some distance apart from the post 73, asshown.

From the above it is evident that the posts 72 and 73 may be veryrigidly secured and braced, and also allowing for the posts to be easilytaken apart when desired and as easily replaced.

The numeral 53 has reference to a girder resting on the forward ends ofthe mudsills 51 and 52 and extending across underneath the machine, towhich it should be blocked up, whereby the sills A and A of the machinemay be additionally supported, as shown.

Secured on the front and rear sides of the post 72 by the bolt 122 (ashort distance above the bolt 104) are the respective eyeplates 123 and124, in which are secured the upper ends of the guy-lines 75 and 7 5.The guy-line 75 extends forward and downward and is secured in theeyebolt 125, said eyebolt being secured in the left-hand portion of thegirder 53, andthe guy-line 75 extends downward and to the rear, where itis secured in the eyebolt 126, the latter being secured in the rearportion of the mudsill 51. Similar unto the above are the guys for thepost 73. Secured on the front and rear sides of the post 73 by the bolt127 (a short distance above the bolt 113) are the respective eyeplates128 and 128, in which are secured the upper ends of the guy-lines 76 and7 6, the former extending downward and forward and is secured in theeyebolt 25, said eyebolt being secured in the right-hand end of vthegirder 53, and the guy-line 7 6 extends down and to the rear, where itis secured in the eyebolt 129, the latter being secured in the mudsill52. y

'Secured on the front and rear sides of the lower portion ofthe post 91by the bolt 130 are the respective eye-plates 131 and 132, in which aresecured the upper ends of the respective guy-lines 133 and 134. Theguyrope 133 extends down and forward and is secured in the eyebolt 135,which latter is secured in the girder 53. The guy-rope 134 extends downand to the rear with. itsrear end secured in the eyebolt 136, whichlatter is secured in the rear end of the mudsill 51, asA

shown. Similar to the above are the guylines for the post 92` Securedonthe front and rear sides of the lower portion of the post 92 by thebolt 138 are the'respective eyeplates 139 and 139, in which are securedthe v upper ends of the respective guy-ropes 137 and 137. The guy-rope137l extends down and forward and is secured in the eyebolt 35, whichlatter is secured in the girder 53. The guy-rope 137 extends down and tothe rear, with its rear end secured in the eyebolt 36, which latter issecured in the rear portion of the mudsill 52, as shown.

Secured on the front and the rear sides of ICO IIO

the upper portion of the post 91 by the bolt 140, Fig. 2, are therespective eye-plates 141 and 142, in which are secured the upper endsof the guy-lines 143 and 144, the former extending downward and forwardand is secured in the eyebolt 145, said eyebolt being secured in theframe 78, which latter may be a part of the engine-frame to be locatedforward of and adjoining the machine, and the guy-line 144 extends downand to the rear, having a hook 146 on its lower end to engage around therear portion of the mudsill 51, as shown in Fig. 1.

Secured on the front and the rear sides of the upper portion of the post92 by the bolt 147, Fig. 10, are the respective eye-plates 148 and 149,in which are secured the upper ends of the guy-lines 150 and 151,thefformer extending downward and forward and is secured in the eyebolt152, said eyebolt being secured in the frame 78, which latter may be apart of the engine-frame, and the guy-line 151 extends down and to therear, having a hook 153 on its lower end to engage around the rearportion of the mudsill 52, as shown in Fig. 9.

Mounted in the frame 93, separate from the channel-wheel 95, as shown,is the small channel wheel or pulley 154, (shown in Fig. 8,) over whichis adapted to operate the rope or cable 11 for operating the sand-pump.

Secured on the front upper edge of the sill A is a boxing 4, in which ispivoted the lefthand endv of the shaft 5, from which point said shaftextends over to the right, and its righthand end is pivoted in the lever6. The

lower end of the lever 6 is pivoted to the inner face of the sill A',from which said lever extends upward a considerable distance, as shownin Fig. 1. Mounted on the left-hand portion of the shaft 5 is the reel10, wi'ic:L is adapted to have wound thereon the rope or cable 1 1. Saidrope or cable extends up from said .reel to the upper portion of themast, passing over said pulley 154, as above vreferred to.

It should be understood that the shaft 5 is pivoted in the lever 6 atapoint above the pivotal connection of said lever with the sill A', fromwhich it is manifest that if the upper end of the lever 6 be moved tothe rear it will cause the frict-ion-pulley which is mounted on theshaft 5 to contact with the bandwheel S and that if the band-wheel S berevolved then the reel 10 will evidently be revolved thereby in a direction opposite to the revolution of the band-wheel, and, on the otherhand, if the lever 6 be moved forward then the reel 10 and its load willbe released. In order that the operation of the lever 6 may be initiatedfrom the most advantageous point, I have provided an arm 15, having itsforward end pivoted to the upper end of the lever 6 and its rear endconnected eccentrically to the shaft 17, said shaft 17 being mountedacross the machine-frame and pivoted to the sills thereof. Said shaft 17is adapted to be rotated by the lever 18, which extends up therefrom,whereby the lever 6 may be given the same movement from this point asfrom the front of the machine.

The means for raising and lowering the derricl; or mast by power' isdescribed as follows: Referring first to Fig. 11, the letter Sdesignates the band-wheel, operative by power located forward to theleft thereof. The band-wheel frame consists of two parallel rails L andM, located directly over and parallel with the respective members A andG of the main frame, above which they are supported by space-blocks, towhich they are permanently connected to the sills aforesaid by means ofbolts or the like. The front and rear ends of the rails L and M areconnected vby metal bands or strips-as, for instance,

and M are boxings P and Q, respectively, inv

which is mount ed the axle R, the band-wheel S being mounted centrallyon said axle. Permanently secured on the right-hand side of theband-wheel S is the channel-wheel U, which is concentric with theband-wheel S and which is adapted to carry in its channeled face thecable-band V. Also mounted permanently on the axle R, to the left of thewheel S, is the reel I/V, adapted to have wound thereon the rope orcable 155. The cable 155 extends upward and rearward with its upper endsecurable to the center of the tie-rod 97, as indicated.

To assist in raising and lowering the mast, I employ a jack-post 200,(shown in Figs. 1, 3, 5, and 9,) which is adapted to be secured in avertical position and whose function will presently be explained. Thelower end of the jack-post is secured in the center of the horizontalbase 201 and is braced thereto by the two braces 202 and 203. The base201 is adapted to rest on the ground immediately in the rear of thespindle 39 and centrally thereof, as shown in Fig. 3. In the apex of thejack-post 200 is mounted the revoluble channel-pulley 204l Secured onthe front and rear sides of the jack-post 200 a short distance below thepulley 204 by the bolt 205 are the respective eye-plates 206 and 207, inwhich are secured the upper ends of the guy-lines 208 and 209, theformer extending downward and forward, with a hook 210 attached on itslower end adapted to engage aroundthe cross-beam D, and the guyline 209extends forward and to the rear, where it may b e secured to a stake orto some other stationary object. (Not shown.) Means for climbing thejack-post is provided for by the pins c and t), which extend outalternately from the sides of said post, as shown.

Means are provided for climbing the mast IOO IIO

ISO

I by the employment of the pins c and d, which .tric with and on theright-hand side of the band-wheel S. Turnbuckles may also be employed inconnection with the guylines,

whereby said lines may be tightened after lbeing secured at their ends.

No reference is made herein to the material of which the various partsare formed, as I reserve the right to use the material that may bethought the best for the purpose or which is the most economical.

Operation: From the above it is apparent 1 that I have provided a mastfor oil-well rigs or drilling-machines which is very easily positionedor removed when desired. Suppose, for instance, that the machine isassembled and the mast is in operative position, as shown in Figs. l, 2,and 3, in order to remove the mast I first position the jack-post 200,securing it as shown and described. I now release all of the guy-ropeswhich support the mast and then allow the mast to tip to the rear, atsame time allowing the rope 155 to pay out from the reel W, the controlof which will be in the province of the operator having in hand thecontrol of the engine or the power for revolving the bandwheel S,thereby allowing the'mast to turn back at the proper rate of speed forsafety. When the mast is being thus lowered and just before it hasreached the position shown in Figs. 5 and 6, the rope 155 will engageover the pulley 204 of the jack-post, as shown in Fig. 5, with whichpulley the rope 155 will engage until the mast has been allowed to restparallel with mudsills or until it has reached a support therefor. Bythe mediation of the jack-post it is evident that the last half of themovement of the mast in being lowered may be accomplished substantiallyas easily as the first half of its movement but without this mediationit would be very difficult to hold the mast, which difficulty wouldincrease as the mast approached a horizontal position. The necessity forthe intermediation of the jackpost is more essential, perhaps, in theraising of the mast, which is accomplished by a converse movement fromthe operation just stated g but in this latter movement, the raising ofthe mast, the band-wheel S is revolved by power in a direction oppositeto the above, thereby causing the rope 155 to wind on the` reel W, andthereby raising the mast to the perpendicular, where it may be securedby the guy-lines as before.

It is also a parent that the -mast may be raised from t e frontrearward, in which instance the jack-post may be placed on the machineby restlng it across the` sills A and A between the members F and D, therope 155 being taken from the reel W and wound on the spindle 39 andalso connecting the band V over the bull-wheel 3 7. Then by treading thebull-wheels by hand the mast may be thereby raised and lowered.

In describing this invention I wish it understood that I have notlimited myself to details, that many changes and modification in theseveral details of construction may be made without in any manneraecting the essential features of the invention, and any such changes aswould come within ordinary mechanical judgment may be made withoutdeparting from the principles of the invention which are claimed as newand useful.
